unfortunately, i went to the local ford stealership, but you can get aftermarket ones for much cheaper. try rockauto.com. a lot of people recommend moog brand, but i noticed they were a little $$...
make sure you get the right ones though. there are different part #'s for torsion bar or coil spring suspension. i'm guessing you have the standard coil spring set-up since it's the 2wd 4-banger like mine. also, diff. part # for left side and right side. don't know why that is but...
fyi, this should probably be in the 2wd suspension forum.
